The PT18H‑V‑K from Cooper Wiring Devices (Eaton) is a professional‑grade 5‑button programmable hour timer engineered to provide automated control of lighting and fan loads while improving energy efficiency and user convenience. This single‑pole electronic timer supports up to 15A (1800W) at 120V AC, making it ideal for managing lighting circuits, ventilation fans, and other compatible loads in both residential and light commercial environments.

Designed as a direct replacement for a standard wall switch, the PT18H‑V‑K requires no neutral wire, significantly simplifying installation in older homes and retrofit projects. Users can select preset countdown times using its five illuminated buttons, and the unit’s LED indicators provide real‑time feedback on the active setting and remaining time. A built‑in bypass mode allows the device to function as a regular ON/OFF switch when needed.

With universal load compatibility, programmable timing modes, and durable construction, this programmable hour timer enhances convenience, safety, and energy savings—making it an ideal solution for bathrooms, laundry rooms, closets, garages, and other spaces where lights or fans are often left on accidentally.

Key Features

• 5 Preset Hour Settings: Features selectable countdown intervals of 1, 2, 4, 8, and 12 hours for automatic shutoff of connected loads. 
• Automatic Shutoff: Automatically turns off lights or fans after the selected time, preventing energy waste. 
• No Neutral Required: Perfect for retrofit installations where a neutral conductor is not available. 
• Universal Load Compatibility: Supports incandescent, halogen, magnetic low‑voltage, electronic low‑voltage, fluorescent, compact fluorescent, LED loads, and motors up to 1/4 HP.
• LED Status Indicators: LEDs display the selected time interval, countdown progress, and alert before shutoff. 
• Bypass/Manual Mode: Allows the timer to operate as a standard ON/OFF switch without countdown. 
• Programmable Time Intervals: Includes quick and advanced programming modes for fully custom timing. 
• Removable Faceplate: Supports optional color‑change kits to match different décor styles. 
• Energy‑Saving Operation: Helps reduce energy consumption and extends lamp/fan life by preventing unnecessary runtime.
